Managing user access
When you pick Authenticated, the User Access drawer slides up. You add the people who can download.
One input does it all
Type an email. As you type, contacts and groups that match show up below the input. Pick from the list, or type any email and click Add to List (or hit Enter).
Add many at once
Paste a list separated by spaces or commas. Each valid email becomes a chip you can remove individually before saving.
Adding a whole group
If you've created Groups in Contacts → Groups, type the group name. A group entry appears in the dropdown with "group · N members" — clicking it adds every member at once (skipping anyone already on the list).
Save the access list as a group
Footer button Save as group turns the current list into a reusable group. If a group with that name already exists you'll be asked to confirm an overwrite.
Recipient limit
Each share has a maximum number of authenticated recipients (shown as N / max in the drawer). When you hit the cap you'll see User Access limit reached. Click Need more? to upgrade — see pricing.
